If you read everything as sarcasm and the opposite, I disgree with the following:

Help Others
Yes! Help others. Even if you think they're doing a bad job, you can help them get better. Everybody starts out as an idiot, not knowing the language, framework or libraries. I know I did.

Point Fingers Privately
Public shaming is hardly ever a good idea. It is demotivating and hardly ever motivates someone to not make mistakes again. Pointing out mistakes/problems is important, but talk to developers privately. If they agree, you share it with the team. Remember, everybody screws up sooner or later.

Do a good job wherever you are. If you're not enjoying your work, not being challenged, are being underpaid, or for any other reason you deem appropriate: find another place to work. People who just complain and don't do anything to try to better their situation will never be happy no matter what the circumstances.
